Choose the sentence that shows proper pronoun-antecedent agreement.

• A. Every student must hand in their assignments on time.
• B. Every student must hand in his or her assignment on time.
• C. Every student must hand in his assignment on time.
• D. Every student must hand in their assignment on time.

Answer: (B)

When matching pronouns to a subject, the pronoun must reflect the number of the antecedent. With a singular antecedent like “Every student,” the referring pronoun should also be singular. Using “his or her” keeps the reference clearly singular and also inclusive of all genders.

In this sentence, after the modal verb must, the base form hand in is correct, and the singular noun assignment matches the singular antecedent. This combination ensures both pronoun agreement and proper verb form.

The other options shift number or gender emphasis: using their with a singular antecedent treats the pronoun as plural; using his alone is gender-specific; and the one with plural assignments can imply more than one assignment per student, which mismatches the singular subject.
